PVI5080N Equivalent & Substitute Parts

Part Overview

The PVI5080N is an optoisolator with photovoltaic output manufactured by Infineon Technologies, rated for 4000Vrms isolation voltage in a through-hole 8-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The part operates across the industrial temperature range of -40°C to 85°C and delivers 8µA output current with a maximum output voltage of 5V.

Substitute Part Grouping Explanation

Substitution for the PVI5080N is determined by the following critical parameters: isolation voltage rating, output type (photovoltaic), number of channels (1), input type (DC), operating temperature range, and mounting compatibility. The substitute parts are grouped into two categories based on isolation voltage alignment:

Category 1 - Direct Equivalent (4000Vrms Isolation): PVI5080NPBF maintains identical electrical specifications and isolation voltage as the main part, differing only in packaging format (Tube vs. unspecified) and product status (Active vs. Obsolete). This part is the primary direct replacement.

Category 2 - Functional Alternatives (Higher Isolation Voltage): APV1122 (5000Vrms) and TLP591B(C,F) (2500Vrms) provide alternative isolation ratings. APV1122 exceeds the isolation requirement with higher voltage rating and improved output characteristics. TLP591B(C,F) operates at lower isolation voltage but offers extended temperature range (-55°C to 125°C) and higher output current (24µA).

Category 3 - Package Variant (Surface Mount Alternative): APV2121S provides photovoltaic isolation in surface-mount format (4-SOP) with 2500Vrms isolation, suitable for applications where through-hole mounting is not required.

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Choice): PVI5080NPBF is the optimal substitute, providing identical electrical and thermal specifications while offering active product status and ROHS3 compliance. This part requires no circuit redesign and maintains the same 8-DIP through-hole footprint.

For Enhanced Isolation Voltage Requirement: APV1122 is suitable when application requirements exceed 4000Vrms isolation. The higher 5000Vrms rating provides additional safety margin. Note the package change from 8-DIP to 6-DIP requires PCB layout modification.

For Extended Temperature Range: TLP591B(C,F) accommodates applications requiring operation beyond 85°C, extending to 125°C maximum. The higher output current (24µA) and output voltage (7V) may require circuit adjustment. Package changes from 8-DIP to 6-DIP with 5 leads.

For Surface-Mount Applications: APV2121S enables integration into surface-mount assembly processes. The 4-SOP package and 2500Vrms isolation are suitable for applications where isolation voltage can be reduced and through-hole mounting is not feasible.

All substitute parts maintain single-channel photovoltaic output configuration and DC input type consistent with the original PVI5080N design requirements.

Frequently Asked Questions (FAQ)

Q: Can PVI5080NPBF be used as a direct drop-in replacement for PVI5080N? A: Yes. PVI5080NPBF maintains identical isolation voltage (4000Vrms), output characteristics (5V max, 8µA), temperature range (-40°C to 85°C), and 8-DIP through-hole package. The only differences are packaging format and active product status.

Q: What are the key differences between the substitute parts? A: Isolation voltage varies: PVI5080NPBF matches the original 4000Vrms; APV1122 provides 5000Vrms; APV2121S and TLP591B(C,F) operate at 2500Vrms. Package types differ: PVI5080NPBF and APV1122 use 8-DIP or 6-DIP through-hole; APV2121S uses 4-SOP surface-mount; TLP591B(C,F) uses 6-DIP with 5 leads.

Q: Is isolation voltage downrating acceptable for APV2121S and TLP591B(C,F)? A: Downrating from 4000Vrms to 2500Vrms is acceptable only if the application circuit design does not require the higher isolation specification. Circuit analysis must confirm that 2500Vrms isolation meets safety and regulatory requirements.

Q: What PCB modifications are required when switching from PVI5080N to APV1122? A: APV1122 uses a 6-DIP package instead of 8-DIP, requiring footprint redesign. Pin count and spacing differ, necessitating PCB layout changes and verification of signal routing.

Q: Are all substitute parts RoHS compliant? A: PVI5080NPBF, APV1122, APV2121S, and TLP591B(C,F) are all ROHS3 compliant. The original PVI5080N is RoHS non-compliant, making these substitutes preferable for new designs subject to RoHS regulations.

Q: Which substitute provides the highest output current? A: TLP591B(C,F) delivers 24µA output current, compared to 8µA for PVI5080N and PVI5080NPBF. This higher current may require circuit adjustment in applications with specific load requirements.

Q: Can APV2121S be used in through-hole designs? A: No. APV2121S is a surface-mount component in 4-SOP package format. Through-hole mounting requires selection of PVI5080NPBF, APV1122, or TLP591B(C,F).
